Functions and Applications
1. XGN15-12 is a unit type sulfur hexafluoride circulating network switchgear. The switchgear employs
FLN36-12D and FLRN36-12D three-working-position SF6 load switch. It is characterized by its compact-design, light weight; nice-looking appearance, easy operation, safe and reliable, long service life, high
performance data, free of pollution and less maintenance.
2. IEC60298 and GB3906 standards compliant.
3. With “Five -prevention” functions, reliable mechanical interlock and the operation errors averting
functions.
4. It is used in electric network (AC, 50Hz, 12kV) to be circulating network and terminal power supply.
5. Latches automatically in three positions (earthing, disconnecting and closing).
